* libxml++/exceptions/wrapped_exception.h: Added comment.
* libxml++/parsers/parser.h:
* libxml++/validators/validator.h: Make handle_exception() private. Then it
will certainly not be considered added API, and it can be included in
libxml++ 2.40.1. Bug #757042.

* Makefile.am: Move most of the contents to the new files. It makes libxml++
more like other mm packages.
* docs/Makefile.am:
* libxml++/filelist.am:
* libxml++/Makefile.am:
* MSVC_Net2010/filelist.am: New files.
* configure.ac: Add the new Makefiles to AC_CONFIG_FILES().
* docs/reference/Doxyfile.in: Remove docs/ from relative paths.

MSVC_Net2005/*:
MSVC_Net2008/*: Remove the whole directories.
configure.ac:
Makefile.am:
.gitignore: Remove MSVC_Net2005 and 2008 files.
It's no longer possible to build libxml++ with MSVC 2005 or 2008, when C++11
features are used. MSVC 2010 is not useful either, but its project files
are kept for now. They can perhaps be useful as a starting point when building
with later MSVC versions. See also libsigc++ bug 754082.
